Following upon our recent work on vector correlations in the Ar-NO collisions [Lemeshko and Friedrich, Phys. Chem. Chem. Phys. 12, 1038 (2010)], we compare model results with close-coupling calculations for a range of channels and collision energies for the He-NO system. The striking agreement between the model and exact polarization moments indicates that the stereodynamics of rotationally ine...

Viviana Zelizer’s recent book, The Purchase of Intimacy (2005), presents an innovative theory of how social and legal actors negotiate rights and obligations when money changes hands in intimate relationships—a perspective that could change how we understand many things, from valuations of homemaking labor to the 9/11 Victim Compensation Fund. This essay describes Zelizer’s critique of the redu...

Recent advancements in Cone Beam Computed Tomography (CBCT) have identified the importance of providing outcomes related to the appropriate use of this innovative technology in dentistry. To assist in determining whether evidence exists, the authors conducted a PubMed search in September, 2012 using the key words “cone beam in Dentistry.” This search revealed 1038 articles with 65 reviews recen...

We describe a simple greedy algorithm whose input is a set P of vertices on a combinatorial surface S without boundary and that computes a shortest cut graph of S with vertex set P . (A cut graph is an embedded graph whose removal leaves a single topological disk.) If S has genus g and complexity n, the running-time is O(n log n+(g + |P |)n). This is an extension of an algorithm by Erickson and...

We demonstrate that the G140L segment B channel of the Cosmic Origins Spectrograph (COS) recently installed on the Hubble Space Telescope (HST) has an effective area consistent with ∼ 10 cm in the bandpass between the Lyman edge at 912 Å and Lyman β, rising to a peak in excess of 1000 cm longward of 1130 Å. This is a new wavelength regime for HST and will allow opportunities for unique science ...

We report a micro-scale procedure for determination of theophylline by use of gas chromatography with nitrogen-sensitive detection. The procedure requires only 10 mul of serum, plasma, or saliva. This sample size makes the determination especially appropriate for monitoring in a pediatric population. With the sample volume used, background interference is equivalent to about 0.1 mg/liter and 0....

In a survey of the UV-brightest AGN using the Far Ultraviolet Spectroscopic Explorer (FUSE), we commonly find associated absorption in the O vi λλ1032, 1038 resonance doublet. Of 34 Type I AGN observed to date with z < 0.15, 16 show detectable O vi absorption. Most absorption systems show multiple components with intrinsic widths of ∼ 100 km s spread over a blue-shifted velocity range of < 1000...

Młodzieżowe rady przy jednostkach samorządu terytorialnego działają praktycznie od 1990 r. Dopiero jednak 2001 funkcjonuje podstawa prawna umożliwiająca powołanie takich organów, ale przez 20 lat pozostawała niezmieniona. Pandemia COVID-19 znacząco ograniczyła możliwość funkcjonowania młodzieżowych rad, które zmagały się z wieloma problemami (np. w wielu przypadkach kończyły kadencje tych a nie...
